Definitions

• the present specification relates generally to agents for coloring and optionally simultaneously lightening keratinic fibers. More specifically, the present application relates to cosmetic agents including cationic anthraquinone dyes and special anionic polymers. The present specification also relates to the use of these agents to produce hair colors having increased shine, an intense color result, improved fastness properties and reduced selectivity.
• either substantive dyes or oxidation dyes may be used for coloring keratinic fibers.
• intense colors with good fastness properties may be obtained with oxidation dyes, the development of the color generally takes place under the influence of oxidizing agents such as H 2 O 2 for example, which in some cases may result in damage to the fiber.
• some oxidation dye precursors or certain mixtures of oxidation dye precursors may have a sensitizing effect on people with sensitive skin.
• Substantive dyes are applied under gentler conditions.
• the disadvantage of these dyes lies in the fact that the colors often have inadequate fastness properties, in particular with regard to hair washing, but also with respect to external influences, such as sunlight, or reactive environmental chemicals, such as swimming pool water, for example.
• coloring or tinting agents are conventionally used which include substantive dyes as the coloring component.
• Substantive dyes are dye molecules which attach directly to the hair and do not require an oxidative process to develop the color. These dyes include henna, for example, which has been known since ancient times for coloring the body and hair. These colors are generally significantly more sensitive to shampooing than oxidative colors, such that an often undesired shift in shade or even a visible decolorization occurs much more quickly.
• Achieving a uniform coloring of hair that has been frequently treated, such as for example bleached or permanently waved hair, where the fibers present differing degrees of pre-existing damage in the various lengths or variously treated areas, represents a particular challenge in terms of coloring hair with substantive dyes.
• the coloring agent may exhibit uneven coloring on hair with differing degrees of pre-existing damage, while repeated hair washing may also cause the dyes to be washed out of the different areas of the hair to varying degrees, resulting in an inconsistent, and hence undesirable, color result.
• the object of the present specification is therefore to provide a coloring agent for keratinic fibers, in particular human hair, which, in addition to other positive fastness properties, has in particular a low selectivity (or a good equalizing capacity) and good wash fastness.
• the colors achieved with the agents according to the present specification should deliver a brilliant and intense color result, both immediately after the coloring process and after repeated hair washes. Following application of the coloring agent, the hair should be uniformly colored, even in cases where the hair exhibits varying degrees of pre-existing damage, wherein this uniformity in the color result should still be present even after repeated hair washes.
• an object was also to provide brilliant and neutral blue shades, or shades in the blue range, with the aforementioned advantageous fastness properties, said shades being extremely suitable for matting.
• the agents should additionally have an optimal viscosity, both with respect to the application process and the coloring capacity.
• the present specification firstly provides an agent for coloring (which may also simultaneously lighten) keratinic fibers comprising, in a cosmetic carrier,
